Here is the original rule

1.	|	rule "Select closest upstream VMS Sign on same route"
2.	|	salience -200
3.	|	no-loop true
4.	|	dialect "mvel"
5.	|	when
6.	|	not IncidentWithVmsSign()
7.	|	$incident : Incident()
8.	|	$incidentRoutingIncreasing : RoutingIncreasing(routeName == $incident.routeName)
9.	|	$sign : VmsSign($incident.routeName == routeName)
10.	|	not VmsSign(($incidentRoutingIncreasing.isIncreasing && $sign.routeMileMarker > routeMileMarker) || (!$incidentRoutingIncreasing.isIncreasing && $sign.routeMileMarker < routeMileMarker))
11.	|	then
12.	|	insert(new IncidentWithVmsSign($incident, $sign));
13.	|	end

Any thoughts would be helpful. David

The rule does seem to fire. Any idea what it is trying to tell me or any 
hints on how to debug this?
